Technical Field
[0001] The invention relates to the technical field of fire extinguishing, and in particular to a fire sprinkler capable of automatically identifying fire and spraying in a directional manner. Background Art
[0002] With the development of social economy and the extensive use of energy, fire has become one of the major accidents that take away human life and property. According to experience and research, the early stage of a fire is the best time to extinguish a fire. If the fire extinguishing system can be released one minute earlier, the effect of suppressing the fire will be greatly increased. To this end, the fire protection field has proposed a variety of implementation methods for extinguishing early fires, such as the common closed sprinkler nozzles and automatic tracking jet fire monitors. Due to its structural characteristics, the former is a 360° ring-mounted spray. When extinguishing the initial point fire, it is impossible to spray all the fire extinguishing agents to the fire source. Although it can achieve fire extinguishing, the required amount is relatively large; without solving the above problems, the latter was invented, which can automatically find the fire source and spray the fire source to achieve rapid fire extinguishing, but while it has comprehensive functions, the cost and volume are also relatively large, and it needs a separate power supply to realize the fire-seeking function, so it has certain limitations in some occasions.
[0003] In summary, a fire sprinkler that can automatically identify fires and spray in a directional manner is proposed to solve the dilemma that early fires are difficult to extinguish in a directional manner. It is easy to install and does not require power supply, thus achieving the effects of saving space, wide application range, and good fire extinguishing effect. Summary of the invention
[0004] In order to solve the above-mentioned deficiencies in the prior art, the present invention proposes a fire sprinkler that can automatically identify fire and spray in a directional manner.
[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: A fire sprinkler capable of automatically identifying a fire and spraying in a directional manner, comprising a sprinkler body and a feed port, wherein the top of the sprinkler body is provided with a feed port, the bottom of the sprinkler body is provided with a circular groove, a one-way fixing device is installed in the circular groove, the bottom of the sprinkler body is further provided with a plurality of circular grooves of the same size, and a flow channel is provided between the circular groove and the feed port for communication between the two; A temperature sensing control device is installed in each of the circular grooves, and the temperature sensing control device is connected to the one-way fixing device. A plurality of nozzles are arranged on the outside of the nozzle body, and the number of the nozzles is consistent with the number of the circular grooves and all of the nozzles are connected to the circular grooves. The nozzles are connected to the flow channel and the horizontal line of the feed port, and the bottom of the nozzle body is connected to a chassis for sealing the nozzle body.
[0006] Preferably, the temperature sensing control device includes a cartridge valve and a temperature sensing glass. The cartridge valve includes a cartridge valve body, a spring, a flow hole and a valve core. The flow hole is on the same horizontal line as the nozzle and the flow channel. The valve core is used to seal the flow hole to block the flow hole from communicating with the nozzle and the flow channel. A spring is provided on the top of the valve core and a temperature sensing glass is connected to the bottom. The temperature sensing glass is used to fix the position of the valve core to prevent it from falling off.
[0007] Its main working mode is that when the temperature-sensitive glass is broken, the cartridge valve core loses its support and automatically falls off. At this time, the system working pressure and the selection spring push the cartridge valve core downward to the clamp ring, and the cartridge valve opens to deliver the fire extinguishing medium. Preferably, the one-way fixing device includes a one-way valve group and a blocking valve, the one-way fixing device is located between two adjacent circular grooves, the two ends of the blocking valve are respectively communicated with the flow hole and are on the same horizontal line, the left and right ends above the one-way valve group are respectively connected to the two sides of the blocking valve below through pipes, and the one-way valve group is used to push the blocking valve to seal the flow hole.
[0008] Preferably, the one-way valve group includes a channel, a one-way valve ball, a one-way valve spring and a one-way valve plug. The one-way valve ball, the one-way valve spring and the one-way valve plug are all located in the channel. The one-way valve ball is used to push the blocking valve to move and seal the flow hole. When the fire sprinkler is working, the fire extinguishing medium presses the one-way valve ball to move downward, so that the fire extinguishing medium flows from the channel to the blocking valve, thereby closing the blocking valve.
[0009] Compared with the prior art, the fire sprinkler of the present invention, which can automatically identify fire and spray in a directional manner, has the following advantages: 1. The fire sprinkler can automatically identify fires in multiple directions and spray fire extinguishing media in a directional manner, which can accurately control the fire.
